The study, conducted by Wageningen University, investigated findings that trees in areas with high Wi-Fi activity (urban areas, especially) were suffering from symptoms that couldn't be tied to typical bacterial or viral causes. The symptoms included bleeding (!), fissures in the bark, the death of parts of leaves, and abnormal growth.

They are not talking about radiation sickness of the type caused by non-ionizing radiation. They are talking about damage caused by RF radiation, which is a real thing. Whether or not RF radiation from wif-fi signals can damage trees is the point of the article. In the one experiment they conducted, the results indicated that it might. The experiment indicates that further study Should. Be. Done.

Right now, the whackers are down the road at a neighbor's house, taking out some dead trees. This is the second time that neighbor has had to have dead or dying trees removed. I may be in that position myself soon. I have some terribly distressed oaks.

The Big Tree wasn’t the biggest known ponderosa alive on Earth, but it might have been the tallest. A ponderosa on the Yakama Indian Reservation, which also recently died, was shorter but considerably stouter and thus the biggest ponderosa in Washington state.
